What do your babies eat during the day? 😬

Hi guys. So my son is technically an October 2018 baby but he was due December 30 (born at 29 weeks) so I think it's right to post here. He has only 2.5 teeth lol. Two at the bottom and one half way out at the top. He's really skinny and it bothers me but the doctor isn't bothered. He's still crawling but doing well in my opinion. He has been between 9 and 10kg since October.

When he wakes up he drinks 180ml toddler formula (nutrilon 4 here in Europe) and then he goes to daycare where he eats cereal, 180ml formula in the afternoon, some fruit and maybe some bread and a small warm meal he takes from home. Because of his lack of teeth, I puree his warm meals. This week, it's green beans, rice and tilapia, usually things like this. When he gets home at 6:30, he doesn't usually eat a whole meal but eats a little bit of whatever we're eating and then goes to sleep with 180ml whole milk.

Is he eating well in your opinion? What else can I feed him to make him add weight? Should I stop the formula? Thanks!
